no sound on a G4 powerbook

no sound on a G4 powerbook

[Maarten de Boer]

Hello,

I try to get alsa working on a G4 powerbook (tumbler).
I use latest CVS, but also tried rc2. Modules load,
i unmute and adjust volume, but alas: no sound.

The dmasound_pmac modules however do work and sound.
But obviously, I want alsa.

I saw a similar message in the achives:

without reply...

Help is greatly appreciated!

Maarten

Is this happening with the CD player?

It is possible that Alsa is set-up for CD Audio to reach
the sound hardware on an analogue line. If the sound
hardware, such  as 'Screamer' does not have such an
input then it may be impossible to raise the CD volume
above zero (check the maximum level quoted in amixer).

Modern Macs do not use analogue connections between the
CD player and the sound hardware, but a digital connection.

There is a patch to xmms that may help.

i hope now it's fixed on cvs.  (it's a really one-liner fix...)
please check out and try once again.
